Your problem is quite different. You seem to have stuck trims? I haven’t seen that, but you may want to check your key assignments for resetting the trim and try to reset them if you haven’t. From what I’ve seen only the rudder trim is reset-able, but all planes should start with neutral trims when you load a new flight.
The issue I reported here has nothing to do with stuck trims, just the rudder trim on some planes that has no effect on the physics, even though you can see the rudder deflected.
